The "Unexpected end of stream"  exception happens when the parser is 
looking for a line in a file, and it can't find it before the file 
ends.  Either there's a bug in the parser, or there is an error in the 
file.

This code doesn't look quite right.  os.path.join joins bits of a path 
together to form a complete path for a file.  Are you sure that this is 
generating a correct filename, and the filename it creates is the name 
of the BLAST format file, and not another file?  If the file that it 
creates is not a BLAST format file, it could very well be reading the 
wrong file and cause the error.
